The purpose of the study was to determine if there was a correlation between principal leadership style and graduation rates of Latino and African American male students. The study also examined the principal leadership style to determine whether or not principal leadership style had an impact on the percentage of students graduating from high school. In addition, the study examined the relationship between principal leadership style as perceived by teachers, counselors, and assistant principals in selected urban and suburban schools located in a Mid west city. The study included two suburban schools selected from a large metropolitan suburban area located in the mid-west with the highest graduation rate from Latino and African American males and two selected urban schools that have the lowest graduation rates in a large metropolitan city in the mid-west during the 2006-2008 school years. The teachers, counselors, and assistant principals were randomly selected from each school. The participants of the study were given the Teacher Perception of Principals Educational Leadership Questionnaire which is used to measure leadership behavior specifically in the area of organization, integration and relationships with subordinates (Ohio State University, 1998). The results of the study were that the suburban schools displayed organization and higher integration leadership was associated with higher graduation rates for Latino males. The results for the urban schools were that no relationship exists between principal leadership styles as received by teachers and Latino and African American males' graduation rates.
